ACTUA'IING DEVICE FOR THE COPS OF SPINNING, TWISTING, AND LIKE MACHINES-,

Application filed June 22, 1925, Serial no; 38,892, and in GermanyA pril 3, 1925.

This invention is concerned with an; actuating device for the cops of spinning, twisting and the like machines; 7

I know that actuating devices have already beenv proposed in which the tooth pressure is by the actuation of the gear in a. certain direction so transmitted that it. is directed against the resiliently springing friction disc. This results in a tilting of the driving gear whereby the teeth of the gear are .fre-' quently damaged. In order to do away with this disadvantage I arrange the gear according to this present invention between two stationary or rigid guiding flanges and have it carried around by friction acting at the inner periphery of the bore. To this end I arrange within the gear sleeve rigidly supportedby its shaft or within the gear itself radially acting springs imparting immediate pressure or imparting it by'means of one or a plurality of pressure members or rings to the adjacent friction surface so that the gearis carried around by friction.

The invention is illustrated in the accompanying drawings in two preferred embodiments. I I Fig. 1. is the cross section of an embodiment at which the springs are located within the sleeve. v V

Fig. 2 is a side view of Fig. 1, the one I flange member being omitted for the sake of better clearness. a Figs. 3 and 4 are the corresponding section "and side view of an embodiment at which flange 5 and, at its central portion, with radial recesses 6 open at one side in order to permit the introduction of the springs 7, even if the worm gear 2 is mounted. The

' springs 7 are acting against one or a plurality of pressure members engaging at the embodiment Fig. 1 the inner per pheralwall V of gear 2 and engaging the outer wall of sleeve 3 according to the embodiment illustrated in Figs. 3 and L. The pressure members carrying around the gear by friction signature;

can be separately arranged for each spring, preferably I arrange a ring 9 slit at one point and having one or a plurality of kerfs IO engaging with correspondingrecesses 11 of the sleeve 3 in order to lock the ring 9 against'peripheral shift on the sleeve 3, as this is illustrated in Fig. 2

The gear 2 is'held by a ring'12 having flanges 13 and being itself attached to the sleeve '3 by one or a plurality of threaded bolts 14, one of'which may be'used forlocking the sleeve-3 on the shaft 4.

Instead of locating the springs 7 within the sleeve 3 the same can also be arranged (i5 within the gear 2 as illustrated in Figs. 3 and 4. In this instance a greater number of springs can be used and the ring 9 is proyided with outwardly directed kerfs 10 look ing it againstshift with relation to the gear 2.

If-the spindle lis arrested for any. reason An actuating mechanism of the kind specilied comprising an annular spindle actuat mounted for rotation, an intermediate friction producing member between the peripheries of .bothmembers, they said sleeve member constituting a lateral guiding and supporting flange for the said worm gear memberat the one side thereof and the one ;of the two members constituting later ally open and radial spring seating recesses, springs within the said recesses and acting ing member so as to produce friction between both members whereby the worm gear.

may be carried around by the said sleeve member upon rotation thGIEQf and alateral disc detachably mounted on the said sleeve member for laterally closing the spring seating recesses and constituting aguiding and supporting flange for the 'worm gear m e1nher at the other side thereof. I
